BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a four-in-one passive mattressmanagement system and method for facilitating various tasks associatedwith beds of all sizes including: making beds; rotating mattresses;holding a bed skirt in place while a mattress is rotated; installing orremoving and re-installing a mattress, for example, in order to replacea bed skirt.

2. Description of the Prior Art

A conventional bed includes a box spring or bottom mattress and an uppermattress. The box spring is normally carried by a bed frame which, inturn, carries a top mattress, which ends up being suspended about 13-16inches from the floor. The top mattress (hereinafter “mattress”) may beplaced on top of the box spring or alternatively placed upon a platformforming a platform bed. In both applications, the mattress is held inplace by friction and its weight.

Various types of mattresses are known. For example, U.S. Pat. Nos.7,617,556 and 7,644,671 disclose conventional mattresses. Suchconventional mattresses include a “casing” which is formed from materialfor holding the internal components of the mattress. The casing includesa bottom panel and four (4) vertical panels connected to the peripheryof the bottom panel forming an open top container. In one suchconventional mattress, a spring core is disposed in the container andrests against the bottom floor and fits snugly against the verticalpanels. One or more layers of foam padding is placed on top of thespring core and covered with a top cover which is secured to thevertical panels.

In other known mattresses, a foam core is used in place of the springcore. The foam core is encased in a zippered encasement. Other knownmattresses are known to include a so-called “pillow-top”. The pillow topis generally formed as a comforter secured to the top cover and filledwith cotton or some type of fibrous material.

A problem with the various types of mattresses, as discussed above, isthat over time the mattress materials lose their resiliency causing bodydepressions to develop. In order to even out the wear in the mattress,it is known to rotate the mattress in the horizontal plane to relocatethe body depressions, as shown for example, in FIGS. 1 and 2. Dependingon the size of the mattress, one or two people may be required to rotatethe mattress. For example, king and queen size mattresses may likelyrequire two people to rotate the mattress, as shown in FIG. 1, whilefull and twin size mattresses can likely be rotated by a single person,as shown in FIG. 2.

Mattresses are relatively heavy items. The weight of a mattress variesas a function of the coil core, the gauge of the coil and the type offoam material used. An average king size mattress weighs between 85 and115 pounds. High end king size mattresses with latex or memory foam canweigh as much as 300 pounds (http://www.mattressdirectonline.com).

In order to rotate a mattress, the mattress must first be lifted andthen rotated, As such, rotating a mattress is hard work. Depending onthe weight of the mattress, rotating a mattress can be virtuallyimpossible for some people, such as senior citizens, as well as peoplethat are handicapped or disabled and others.

In order to address this problem, mattresses with removable pillow topshave been developed. An example of such a mattress is disclosed in U.S.Pat. No. 5,414,882. The '882 patent discloses a mattress with a pillowtop that is secured to the top cover of the mattress by way of a zipper.With such a configuration, the pillow top can be relatively easilyrotated by unzipping the pillow top, rotating it and zipping the pillowtop back in place. While such a configuration enables body depressionsin the pillow top to be relocated, it has no effect on body depressionsthat result in the mattress itself. Thus there is a need for a system tofacilitate rotation of a mattress.

FIGS. 1-26 relate to other aspects of the invention. For example, FIGS.2-12 illustrate a two cover embodiment of the invention. FIGS. 21, 22and 72, 73 relate to encasement embodiments of the invention. FIGS. 25,26 and 44 illustrate a one cover embodiment of the invention. FIG. 32illustrates an embedded embodiment of the invention while FIG. 45relates to a two cover embodiment in which only one cover is embedded.

Mattress Management System

The present invention relates to a mattress management system. Asmentioned above, the mattress management system enables the followingtasks to be performed with respect the mattress. These tasks include:

-   -   passive bed making    -   installing or removing and re-installing a mattress, for        example, in order to replace a bed skirt.    -   rotating the mattress in a horizontal plane    -   in applications where bed skirts are used, holding the bed skirt        in place.

The mattress management system may be implemented with conventional bedssupported by a box spring or with fixed or adjustable platform beds. Inaddition, the mattress management system may be implemented with onecover or two cover and with a cover embedded in the underside of themattress or the foundation. FIGS. 21, 22 and 72, 73 illustrateembodiments in which the cover is embedded in an encasement.

One or more of the various permutations of the invention as discussedherein can be combined to form a mattress management system inaccordance with the present invention. All such combinations areconsidered to be within the broad scope of the invention. It is to beunderstood that only exemplary combinations of those permutations areillustrated and discussed below.

FIG. 12 illustrates mattress rotation in an embodiment with two covers.In this embodiment, a bed skirt 36 is disposed over the foundation. Asdiscussed below, the cover 22 holds the bed skirt 36 in place while themattress 28 is rotated. FIGS. 27 and 28 illustrate mattress rotation inan embodiment with one cover. FIG. 33 illustrates mattress rotation in atwo cover embodiment in which one cover is embedded.

FIGS. 34 and 35 illustrate mattress rotation with a one coverembodiment. In this embodiment, a single cover 206, as described belowis attached to the foundation 202. As shown, a bed skirt 204 is disposedover the foundation 202. During rotation, as illustrated in FIG. 35, thecover 206 holds the bed skirt 204 in place.

FIGS. 36-41 illustrate removal of a mattress 200 in order to change thebed skirt 204. As shown in FIG. 36, a single cover 206 is attached tothe foundation 202 so that a slick side of the cover 206 faces theunderside of the mattress 200. As illustrated by the arrows 201 in FIGS.37 and 38, the mattress 200 is off the foundation 202. At some point themattress will rotate and one edge of the mattress 200 will touch theground. As illustrated in FIG. 39, the mattress is then rotated, asindicated by the arrow 212 additionally, as indicated by the arrow 212,until it is clear of the foundation 202 as shown. Preferably, theposition of the mattress 200 is stabilized by placing a top edge 214 ofthe mattress 200 against a wall (not shown). The cover 206 is thenremoved along with the existing bed skirt 204. Next, a new bed skirt 204is placed on the foundation 202. The cover 206 is re-installed to thefoundation 202, over the cover 204 so that a slick side of the cover 206faces upward. The mattress 200 is then rotated in the direction of thearrow 218 until gravity causes the mattress 200 to fall onto thefoundation, as indicated in FIG. 40. The mattress 200 is then slid intoposition, as indicated by the arrows 220, as illustrated in FIG. 41. Thecover 204 may be detached from the foundation and attached to theunderside of the mattress so that a rough or non-slick side is incontact with the bed skirt. FIGS. 81-86 are similar to FIGS. 36-41 butillustrate the mattress covered with an encasement as illustrated inFIG. 21, 22 or 72, 73.

Single Cover Embodiments

In one embodiment of the invention, a single cover may be used tofacilitate rotation of a mattress in a horizontal plane carried by a boxspring or a fixed or adjustable platform. Multiple embodiments of thesingle cover version are provided. In one embodiment, a slick surface isembedded in the mattress, box spring, platform, encasement, asillustrated in FIG. 21, or the mattress cover with zip-in bottom panel,as illustrated in FIGS. 42 and 43. In an alternate embodiment, theinvention relies on the inherent surface characteristic of either themattress, box spring, platform, encasement, as illustrated in FIG. 21,or the mattress cover with zip-in bottom panel, as illustrated in FIGS.42 and 43.

Embedded Slick Surface

In addition to the embodiments discussed below which require two covers,alternate embodiments are discussed below which require only one cover.For example, one of the covers 20, 22 (FIGS. 3-11) may be eliminated anda slick surface embedded into the box spring or platform. In anexemplary embodiment, the box spring or platform includes an integral orembedded slick surface facing upwardly and is configured to contact themattress. In such an embodiment, a single cover 20, as described below,may be attached to the underside of the mattress such that the slicksurface faces downwardly and the non-slick surface is in contact withthe underside of the mattress In a rotate mode of operation, the slicksurface of the cover 20 is in contact with the slick surface integrallyformed in the box spring or platform. Once the mattress is rotated andin the desired location, the cover 20 is attached to the box spring orplatform so that the two slick surfaces are in contact with each otherand the non-slick surface is in contact with underside of the mattressdefining a normal mode of operation. Alternatively, the slick surfacecan be embedded into mattress and in contact with the slick side of thecover.

Alternative Single Cover Embodiment

In this embodiment, a single cover can be used with one slick side andone non-slick side. In such an embodiment, the invention relies on theinherent surface roughness and friction of either the mattress, boxspring, platform, encasement, or mattress cover with zip-in panel. In anembodiment with a cover having two slick surfaces, the cover is attachedto either the mattress, box spring, platform, encasement, or mattresscover with zip-in panel and remains in place during both a rotate modeand a normal mode. Additional means, as discussed below, are provided tosecure the mattress with respect to the box spring or mattress toprevent unintended movement of the mattress.

An alternative embodiment of the single cover invention utilizes a coverhaving a slick side and a non-slick side. The cover is attached toeither the mattress, box spring, platform, encasement, or mattress coverwith zip-in panel. In this embodiment, the invention relies on theinherent surface roughness of either the mattress, box spring, platform,encasement, or mattress cover with zip-in panel. For example, in anormal mode of operation, the cover may be attached to the mattress,encasement, or mattress cover with zip-in bottom panel so that itsnon-slick side faces outwardly and contacts the inherent surfaceroughness of the box spring or platform to prevent unintended movementof the mattress. In a rotate mode of operation, the cover is attached tothe box spring or platform so that the slick surface contacts themattress, encasement, or mattress cover with zip-in bottom panel and thenon-slick side contacts the box spring or platform. As mentioned above,in this embodiment, the invention relies on the inherent surfaceroughness of the mattress, encasement, or mattress cover with zip-inbottom panel. The mattress is rotated and the cover is re-attached tothe mattress, encasement, or mattress cover with zip-in panel.

An exemplary embodiment of the invention is described below. In oneexemplary embodiment shown, FIGS. 25-30 b illustrate an embodiment ofthe invention on a fixed platform. FIGS. 31 c-32 illustrate anembodiment of the invention on an adjustable platform.

As illustrated in FIGS. 25 and 26, the cover, generally identified withthe reference numeral 100, includes a rectangular portion 102. Anattachment portion may be used to secure the rectangular portion inplace with respect to the box spring or mattress. The attachment portionmay be implemented as a side portion 104, as discussed below, or variousother means, also discussed below and virtually any means that cansecure the rectangular portion 102 of the cover 100 with respect to theplatform or box spring or mattress. The rectangular portion 102 of thecover 100 is formed to fit a fixed platform 106 (FIG. 25) or anadjustable platform 108 (FIG. 29 a) or a box spring. The side portion104 may be continuous around the perimeter of the rectangular portion.In the exemplary embodiment shown, at least a portion of the rectangularportion 102 or the entire rectangular portion 102 includes a slicksurface 108 on one side and may include at least a portion or the entireopposing side may form a non-slick surface 110.

The generally rectangular portion 102 of the cover 100 may be formedfrom a 70D×70D T210 nylon ripstop material or other material withsimilar non-elastic properties. The size of the rectangular portion 109may be selected to be the same size as the horizontal portion 111 of theplatform 106.

At least a portion of one side of the generally rectangular portion 102may be coated to form the slick side 109. The slick side 109 may beprovided by way of various coating including a silicone coating or othercoating providing a similar co-efficient of friction. The siliconecoating is optional on the slick side 109. The inherent surfaceroughness of the material may be used alone as the slick side 109. Atleast a portion of the other side of the generally rectangular portion102 may be formed as a non-slick side 110. The non-slick side may beprovided by various coatings including a polyurethane coating or apolyvinyl chloride (PVC) coating or other coating having a similarco-efficient of friction. Alternatively, materials which inherently havea slick side and a non-slick side may be used without any coatings.

The side portion 104 may be formed from various elastic materialsincluding 90 gram, 100% polyester material, otherwise known as JerseyKnit or other materials having similar elasticity properties. One sideof the side portion may optionally be coated with a non-slick coating,such as 1-3 mil of polyurethane or PVC. The optional coating is appliedto a side that will be in contact with the platform 106. The sideportion may be made from the same material as the sides of the mattress,encasement, or mattress cover with zip-in bottom panel.

The side portion 104 is attached around the perimeter of the rectangularportion 102 to secure the generally rectangular portion 109 in placeover the platform 106 or 108 (FIG. 29 a, 30 a). As shown, the sideportion 104 may be provided with a width generally equal to the width ofthe vertical rails forming the platform 106 or 108 (FIG. 29 a, 30 a).

The function of the side portion 104 is to hold the generallyrectangular portion 109 in place. Other means can be used to hold therectangular portion 109 in place relative to the platform 106 or 108 ina rotate mode of operation or alternatively with respect to the mattressin a normal mode of operation. For example, various fasteners includingVelcro fasteners, snaps, buttons and the like can be used. Virtually anytype of fasteners are suitable, including fasteners, for example, asdisclosed in http:/www.questoutfitters.com/plastic.htm. Also, straps,for example, nylon webbing, with or without buckles, d-rings, orfasteners can be used. All such devices are considered to be within thebroad scope of the invention.

As shown in FIGS. 25 and 26, in a rotate mode of operation, the cover102 is attached to the platform 106 so that the non-slick surface 110 ofthe cover 102 is in contact with the horizontal portion 111 of theplatform 106 defining a rotate mode of operation. If an optionalcoating, as discussed above, is applied to the side portion 104 of thecover 102, the optional coating (not shown) will be in contact with thevertical rails of the platform 106.

Referring to FIGS. 27-30 a, operation of the single cover embodiment isillustrated. FIGS. 27 and 28 illustrate a rotate mode of operation. In arotate mode of operation, the cover 104 is attached to the platform 106or 108 (FIG. 30 a). As mentioned above, in this mode of operation, theslick side 109 of the cover 100 (FIG. 25) is in contact with theunderside of the mattress 112. As such, a user can rotate the mattressrelatively effortlessly, as indicated by the arrow 113. FIGS. 77 and 78are similar to FIGS. 27 and 28 but illustrate the mattress encased in anencasement as illustrated in FIG. 21, 22 or 72, 73. FIGS. 79 and 80 aresimilar to FIGS. 34 and 35 but illustrate the mattress encased in anencasement as illustrated in FIG. 21,22 or 72,73.

FIG. 28 illustrates the mattress 112 in place after rotation. After themattress 112 is in place, the sides 104 of the cover 100 (FIG. 25) areattached to the mattress 112, as shown in FIGS. 29 a and 30 a,illustrating a normal mode of operation. FIGS. 29 b and 30 b are similarto Figs. FIGS. 29 a and 30 a but illustrating the mattress encased in anencasement as illustrated in FIG. 21, 22 or 72,73.

FIGS. 31 a and 31 b illustrate a conventional bed on an adjustableplatform. The adjustable platform bed, generally identified with thereference numeral 390, includes a foundation 394. The foundation 394includes a base 396 and an adjustable platform 398. The adjustableplatform 398 is mechanically supported by the base 396. Electric motors(not shown) are used to adjust the position of the adjustable platform396. The mattress 392 is known to have a zip-out panel 408. One or moreslick surfaces may be incorporated into the adjustable platform bed 390to facilitate bed making. Specifically, the adjustable platform 398 maybe covered with a relatively a material having a relatively slicksurface. The zip-out panel 408 may be alternatively or in addition bereplaced by different panel (not shown) with a slick surface. One orboth of these slick surfaces can be used to facilitate bed making, thusforming a passive bed maker. In such a configuration, the mattress 392may be secured to the platform 398, for example, with conventionalfastening means, such as a zipper or other means.

The exemplary platform 398 is illustrated in FIG. 31 c. The adjustableplatform 398 includes a plurality of sections 114, 116, 118 and 120which are movable about the various axes 122, 124 and 126. Variousmechanical drives (not shown) are located beneath the platform 108 thatenable the various sections to be adjusted by way of a controller (notshown). FIG. 31 c illustrates the adjustable platform 398 in a sleepposition in which all of the adjustable sections 114, 116, 118 and 120are flat defining a sleep position.

FIG. 32 illustrates the application of the single cover embodiment to abed with an adjustable platform 398 (FIG. 31 c). The cover 100 functionson an adjustable platform 398 in the same manner as a fixed platform 106(FIG. 25). In particular, the cover 100 is attached to the adjustableplatform 109 with the adjustable platform in a sleep position. In arotate mode of operation, as generally illustrated in FIG. 32, the cover100 is attached so that the slick side 109 faces upwardly and contactsthe underside of the mattress 112. The mattress 112 is rotated, forexample, in the direction of the arrow 114, relatively easily. Once themattress 112 is in position, as shown in FIG. 30, the cover 100 isattached to the mattress 112, as shown in FIGS. 29 a, 29 b and 30 a, 30b, defining a normal mode of operation. FIG. 33 is similar to FIG. 32except an additional cover with a relatively slick surface is embeddedin the underside of the mattress 112. The slick surface on the embeddedcover (not shown) co-operates with a slick surface on the cover 109 whenthe cover 109 is attached to the foundation 104. Once the mattress isrotated, the cover 109 is detached from the foundation and attached tothe underside of the mattress 112, so that a non-slick surface of thecover 109 is in contact with the foundation.

Two Cover Embodiment

In a two cover embodiment of the invention, as illustrated in FIGS.3-11, the slick surfaces may be provided by two (2) separate covers; onecover for the mattress and one cover for the box spring or platform. Onecover is provided with a slick and non-slick side. The other cover isprovided with at least one slick side and may have two slick sides. Inan alternate embodiment, as shown in FIGS. 21 and 22, one cover may be aprotective cover, such as an encasement, that encapsulates the entiremattress and permanently exposes a slick surface relative to the boxspring or platform. In another alternate embodiment, one cover may beprovided that cooperates with a slick surface that is integrallyprovided on one or the other of the mattress or box spring or platform.In yet another alternate embodiment of the invention, as shown in FIGS.12-20, slick surfaces may be provided on both the mattress and the boxspring or platform. In this embodiment, in order to prevent movement ofthe mattress with respect to the box spring or platform, the mattress issecured relative to the box spring or platform by removable fasteners ina normal mode of operation.

In the embodiments illustrated in FIGS. 3-11 and 21-22, two (2) coversare provided which enable slick surfaces between the mattress and thebox spring or platform to be selectively placed in contact with eachother to reduce the normal friction therebetween to enable the mattressto be rotated in a horizontal plane without lifting the mattress.Alternate embodiments, operate on the same principle but require onlyone separate cover that cooperates with a slick surface integrated intoone or the other of the mattress or box spring or platform. In yet otherembodiments of the invention, as illustrated in FIGS. 13-20, the slicksurfaces on the mattress and box spring or platform are constantly inengagement with each other when the mattress is placed on top of the boxspring or platform. In these embodiments, one or more fasteners, asdiscussed below, are used to secure the mattress to the box spring orplatform to prevent unintended movement therebetween in a normal mode ofoperation.

Referring first to FIGS. 3-5, the invention comprises a first cover 20and a second cover 22. The covers 20 and 22 each include a rectangularpanel 24 and 26, respectively, configured to the size of a mattress 28and a box spring 30. Each of the covers 20, 22 includes a band 32, 34,attached to the periphery of the panels 24, 26 respectively. The bandsor side panels 32, 34, allow the covers 20, 22 be removably secured tothe mattress 28 and the box spring 30, as generally shown in FIG. 4.

The bands or side panels 32, 34 can also be formed from an elasticmaterial, for example, spandex and other stretchable materials, such asmesh or an elastic band and attached to the panels 24, 26 respectively,for example, by sewing. Alternatively, the bands 32, 34 can be formedfrom a mesh or stretchable fabric. The bands 32, 34 can also be formedfrom the same material as the panels 24, 26 or same materials as sidesof the mattress, mattress encasement, or box spring and secured to themattress 28 and box spring or platform 30 by way of the verticalattachments methods, as discussed below. Horizontal attachments methodsmay also be used to tighten the grip of the cover with respect to themattress, box spring, or foundation. The single cover and coverlessembodiments, including aftermarket encasements and mattress covers withzip-out bottom panels as discussed above may also include the attachmentmethods described in conjunction with the two cover embodiment.

The bands 32 and 34 may also be formed by less labor-intensive methods,as illustrated in FIGS. 23 a-23 b and FIGS. 24 a-24 c. The methodsillustrated in these figures, reduce the amount of sewing and thus thelabor involved. For simplicity, only one cover 20 is described andillustrated. Referring first to FIGS. 23 a and 23 b, one corner of acover blank, generally identified with the reference numeral 21, isillustrated for simplicity. The cover blank is formed as a generallyrectangular piece of material with fold lines, generally identified withthe reference numeral 23, adjacent to each edge of the rectangular pieceof material. As shown in FIG. 23 a, a piece of material is cut out ofeach corner defining, for example, an obtuse angle. The cut-out isidentified with the reference numeral 25. The bands 32′ are folded downas shown in FIG. 23 b. A piece of flexible material, such as elastic,identified with the reference number 27, is used to bridge the cut-out25. The flexible material 27 is secured to the ends of the contiguousbands 32′. As will be appreciated by those of ordinary skill in the art,the embodiment illustrated in FIGS. 23 a and 23 b significantly reducesthe labor costs.

A second technique to reduce labor costs is illustrated in FIGS. 24 a-24c. In this embodiment, the corners of the material blank 21′ are cut toform a cut-out 25′ that is not an obtuse angle. The exemplary cut-out25′ is shown at roughly a 90 degree angle. In this embodiment, afastener strip 29 is affixed to each end of the band 32″, adjacent thecut-out 25′. A cooperating removable fastener strip 31 may be attachedto the fastener strips 29 to secure the adjacent bands 32″ together. Thefastener strips 29 and 31 may be Velcro or other type of fastener. Theembodiment illustrated in FIGS. 24 a-24 c allows the material blank 21′to be juxtaposed over the mattress 28 or box spring 30 with theremovable fastener strips 31, as least partially removed, for example,as shown in FIG. 24 b. and secured to the exposed cooperating fastenerstrip 29, or any of the attachment methods discussed below.

FIGS. 24 e-24 j illustrate various techniques to tighten the grip of thecover, for example, the one cover mattress management system describedherein, with respect to a mattress or foundation. Other attachmentmethods are discussed below. As shown in FIGS. 24 d and 24 e,conventional fasteners, such as snaps, Velcro or buttons, generallyidentified with the reference numeral 504 are rigidly affixed to themattress 500 and/or the foundation 502. Mating fasteners 506 may beprovided on the cover 503. As shown in FIG. 24 d, the cover 503 isattached to the foundation 502. As the cover 503 is attached to themattress 500, the mating fasteners 500 and 506 are joined together tosecure the cover 503 relative to the mattress, as illustrated in FIG. 24e. It is also contemplated to dispose additional mating fasteners on thecover 503 and the foundation to secure the cover 503 to the foundation502. FIGS. 24 m and FIG. 24 n are similar to FIGS. 24 d and 24 e butillustrate the mattress encased in an encasement illustrated in FIG. 21,22 or 72, 73.

FIGS. 24 f and 24 g are similar to FIGS. 24 d and 24 e. In thisembodiment, the cover 503 is not provided with full side panels 505, asillustrated in FIGS. 24 d and 24 e, but rather corner flaps, generallyidentified with the reference numeral 507.

FIGS. 24 h and 24 i illustrate different exemplary techniques forproviding a tight grip between the cover 503. In these embodiments, atleast two of the side panels 509, 510 are not attached together, asshown. In FIG. 29 h, the end of one side panel 509 includes a loop 512.The adjacent side panel 509 includes a plurality of buttons, generallyidentified with the reference numeral 514, for receiving the loop 512.The grip of the cover 503 is adjusted depending on the particular buttonselected to catch the loop. FIG. 29 i is similar but utilizes adrawstring 514, or other attachment method as discussed below, totighten the grip of the cover 503 with respect to a mattress orfoundation.

FIGS. 24 k and 24 l are similar to FIG. 24 h but illustrate the use ofthe buttons 514 with one or more cooperating buttonholes 515.

FIG. 24 j illustrates a cover 503 in which all of the side panels areconnected forming a fitted sheet. In this embodiment, each side panelmay include a strap and Velcro, as generally indicated by the referencenumeral 516. In this embodiment the strap can be tightened and attachedto the Velcro in the tightened position to tighten the grip of the cover503 relative to the mattress 518 or foundation (not shown.

In accordance with an important aspect of the invention, one cover 20,22 has a “slick” side having a relatively low co-efficient of frictionand a non-slick side having a relatively higher co-efficient offriction. The other cover 20, 22 has at least one slick side and mayhave two slick sides. As such, when the slick surfaces of the two covers20, 22 are selectively placed in contact with each other, the mattress28 can be rotated in a horizontal plane with minimal effort by oneperson in a configuration defining a rotate mode of operation, asdiscussed in more detail below. The non-slick side is used toselectively be placed in contact with an uncovered surface of themattress 28 or an uncovered surface of the box spring 30 or platform orbed skirt. The non-slick side provides a relatively high co-efficient offriction when in contact with either an uncovered surface of the boxspring 30 or an uncovered surface of the mattress 28 or bed skirt (FIG.6) or platform (FIGS. 12 and 76) in order to reduce if not preventunintended rotation of the mattress in a normal configuration.

Referring to FIG. 4, a first cover 20 is attached to the undersidemattress 28 so that its non-slick side is in contact with the mattress28 and its slick side is facing downwardly. Similarly, the cover 22 isattached to the box spring 30 so that its non-slick side is in contactwith the box spring 30 and its slick side is facing upwardly.Alternatively, the covers 20, 22 may be provided with two slick sides.In such an embodiment, one slick side is in contact with the mattress28, box spring 30, respectively, and the other slick side is facingdownwardly or upwardly, respectively.

When the mattress 28 is then brought into contact with the box spring30, as generally illustrated in FIG. 5, the slick sides of the covers 20and 22 will be in contact with each other, enabling the mattress 28 tobe rotated in a horizontal position with reduced effort by a singleperson defining a rotate mode of operation.

Once the mattress 28 has been rotated and is in the desired position,the top cover 20 may be detached from the mattress 28 and attached tothe box spring 30 over the cover 22. This places the non-slick side ofthe cover 20 in contact with an uncovered surface of the mattress 28,thereby reducing unintended rotation of the mattress 28 with respect tothe box spring 30. In this configuration, both covers 20 and 22 areattached to the box spring 30. Alternatively, in embodiments in whicheach of the covers has a slick side and a non-slick side, once themattress 28 is in the desired position, the bottom cover 22 can bedetached from the box spring 30 and attached to the mattress 28 over thecover 20, exposing the non-slick side of the cover 22 to the box spring30. In this configuration, both covers 20 and 22 are attached to themattress 30.

FIGS. 6-8 illustrate operation of the covers 20 and 22 in an applicationin which a bed skirt 36 is draped over the box spring 30, as generallyshown in FIG. 6. Heretofore rotation of a mattress 28 with a bed skirt36 draped over the box spring 30 was a relatively cumbersome task. Thepresent invention greatly simplifies rotation of the mattress 28 in suchan application while keeping the bed skirt 36 in place.

More specifically, in this application, the first cover 20 is attachedto the underside of the mattress 28 so that its slick side is facingdownward and its non-slick side (or alternatively its second slick side)is in contact with the mattress 28. The second cover 22 is attached tothe box spring 30 over the bed skirt 36 so that its non-slick side is incontact with the bed skirt 36 and its slick side is facing upward,thereby placing the slick sides of the covers 20 and 22 in contact witheach other, as shown in FIGS. 7 and 74. The mattress 28 can then berotated with reduced effort, as generally illustrated in FIGS. 12 and76.

After the mattress 28 is rotated to the desired position, the cover 22is detached from the box spring 30 and attached to the mattress 28 overthe cover 20, as shown in FIG. 8. This places the non-slick side of thecover 22 in contact with the bed skirt 36 to reduce if not preventunintended rotation of the mattress 28. As shown in FIGS. 8 and 75, thebed skirt 36 is uncovered and undisturbed since the cover 22 holds thebed skirt 36 in place during the rotation of the mattress 28.

FIGS. 9-11 are similar to FIGS. 6-8 and illustrate another applicationin which the bed skirt is used to hide the first and second covers 20and 22 in a normal configuration. Referring to FIG. 9, the bed skirt 36is disposed around the mattress 28 so that its finished side is incontact with the mattress 28 and its unfinished side is facingoutwardly. The first cover 20 is attached to the mattress 28 over thebed skirt 36 so that its non-slick side is in contact with the bed skirt36 and its slick side is facing downwardly. The second cover 22 isattached to the box spring 30 so that its non-slick side is in contactwith the box spring 30 and its slick side is facing upwardly, thusplacing the slick sides of the first and second covers 20 and 22 incontact with each other. The mattress 28 can then be rotated in ahorizontal plane virtually effortlessly by one person. Once the mattress28 is in the desired position, the first cover 20 is detached from themattress 28 and attached to the box spring 30, over the second cover 22,as shown in FIGS. 10 and 11. This places the non-slick side of the firstcover 20 in contact with the bed skirt 28, in contact with the mattress,thereby reducing unintended rotation of the mattress 28. Once the firstcover 20 is attached to the box spring 30, the bed skirt 36 is foldeddown over the box spring 30, thereby hiding both the first and secondcovers 20 and 22, as shown in FIGS. 10 and 11.

FIGS. 21, 22 and 72, 73 illustrate an embodiment in which the firstcover is replaced with a protective cover 40, such as a protectivecover, that encapsulates the mattress 28. The protective cover 40 is tosize and shape of the mattress 28 to provide a relatively snug fit. Anopening 42 is provided along one edge of the protective cover 40 toenable the mattress 28 to be placed inside the protective cover 40. Aconventional fastener, such as a zipper 44 may be used to close theopening 42. In this embodiment, one surface 46 of the cover 40 may beprovided with a slick surface 46. The mattress 28 and cover 40 isconfigured so that the slick surface 46 faces the box spring 30. Theslick surface 46 of the cover 40 cooperates with the cover (FIGS. 72,73) attached to the box spring 30 to facilitate rotation of the coveredmattress 28 in a rotate mode. The cover 22 is as described above with aslick surface and a non-slick surface. More particularly, in a rotatemode of operation, the cover 22 is attached to the box spring 30 so thatits non-slick surface is in contact with the box spring 30 and the slicksurface faces upwardly in order to contact the slick surface of theprotective cover 40. In this mode, the mattress 28 can be rotated withreduced effort in a horizontal plane. Once the mattress 28 has beenrotated to the desired position, the cover 22 is attached to themattress 28 causing its non-slick surface to be in contact with the boxspring 30.

Coverless Embodiment

The embodiments discussed above are based on the use of one or morecovers which can be selectively configured in a rotate mode of operationor alternatively a normal mode of operation. In the embodimentsillustrated in FIGS. 13-20, there are no covers. In these embodiments,slick surfaces 50 and 52 are integrally provided on the mattress 28 andbox spring 30, respectively, or aftermarket encasement, as illustratedin FIGS. 21 and 22, or the zip-out bottom panel 367, as illustrated inFIGS. 42 and 43. In particular, as best shown in FIG. 13, the mattress28 is formed with an integral slick surface 50 on it is underside.Similarly, the box spring 30 can be formed with integral slick surface52 facing upwardly. As such, when the mattress 28 is properly placed onthe box spring 30, the slick surfaces 50 and 52 are in contact with eachother. In such a configuration, the mattress 28 can be freely rotatedwith respect to the box spring 30.

In order to prevent movement of the mattress 28 with respect to the boxspring 30 in a normal mode of operation, fastener systems, for example,Velcro fasteners, may be provided on the corners of both the mattress 28and the box spring 30. In particular, permanent fastener strips 54 areprovided on the corners of the mattress 28, as shown in FIGS. 13, 14 and16. Similarly, permanent fastener strips 56 are provided on the cornersof the box spring 30. As shown in FIGS. 13, 14 and 16, when the mattress28 is correctly aligned with the box spring 30, the permanent fastenerstrips 54 are aligned with the permanent fastener strips 56. In order tosecure the mattress 28 relative to the box spring 30, removablecooperating fastener strips 58 are selectively attached to the permanentfastener strips 54 and 56 as shown in FIGS. 15 and 17 defining a normalmode of operation. The removable fastener strips 58 are simply removedin order to rotate the mattress 28 and replaced once the mattress 28 hasbeen rotated.

FIGS. 51 and 52 illustrate are similar to FIGS. 13-15 but illustrate amethod of securing the foundation 30 to the mattress using the verticalattachment method as illustrated in FIG. 46.

Two alternate embodiments are illustrated in FIGS. 18-20. In theembodiment illustrated in FIGS. 18 and 19, permanent fastener strips 60and 62 are located around the peripheries of the mattress 28 and the boxspring 30, adjacent to the edges where the mattress 28 and the boxspring 30 come together, as shown in FIG. 18. As shown in FIG. 19, acooperating removable fastener strip 64 is attached to the permanentfastener strips 60 and 62 on the mattress 28 and box spring 30,respectively. In yet another alternate embodiment as shown in FIG. 20,the cooperating removable fastener strip 64 may be affixed to the insideof a bed skirt 66. With such a configuration, not only are the mattress28 and box spring 30 secured together, the configuration also allows abed skirt 66 to be easily installed.

Attachment Means

Various vertical and horizontal attachments are disclosed herein.Horizontal attachments are used to secure side panels together, forexample as illustrated in FIGS. 23 a-24 c, 24 h, 24 i, 24 k, and 24 l.Other attachment means such as illustrated in FIG. 24 j may be used aswell. Such horizontal attachments may also be used to tighten the gripof the side panels of the cover, or optionally the encasement, to amattress or a foundation.

Vertical attachments are used to secure a cover to a mattress (FIGS. 46,56, 60, and 67); a cover to a mattress with a zip out bottom panel(FIGS. 47, 58, 61, and 69); and an aftermarket encasement (FIGS. 48, 53,62, and 68). Various other vertical attachments are illustrated forattaching a cover to a mattress (FIGS. 24 m, 24 n) and a mattresscovered with an aftermarket encasement (FIGS. 24 o and 24 p).

In addition, a flip panel, straps, or other members (not shown) caneither be attached to a mattress, mattress cover, encasement, orfoundation. A fastener system can be imbedded in the flip panel, straps,or other members that cooperates with a mating fastener such as azipper, buttons, buckles, or other fasteners to a cover or thefoundation to secure the mattress to the foundation or to secure a coverto the mattress, mattress cover, or encasement, or foundation.

All fastener systems described and illustrated herein are suitable forboth the vertical and horizontal attachments for all embodiments of theinvention and can be used interchangeably or in combination with eachother.

Obviously, many modifications and variations of the present inventionare possible in light of the above teachings. For example, materials forthe covers and slick surfaces other than those mentioned above can bewhich have similar co-efficient of friction characteristics. Thus, it isto be understood that, within the scope of the appended claims, theinvention may be practiced otherwise than as specifically describedabove.

What is claimed and desired to be secured by a Letters Patent of theUnited States is:

I claim:
 1. A method for passive management of a mattress supported by afoundation, comprising the steps of: incorporating at least one coverinto a mattress or foundation which facilitates mattress rotation.
